JOHN LOGAN,

APPARATUS FOR COLORING STEEL RIBBONS.

SPECIFICATION forming part of Letters Patent No. 510,352, dated December 5, 1893. A

Application filed March 28, 1892. "Serial No. 426,741. (No model.) 7

To all whom it may concern.-

Be it known that I, JOHN LOGAN, of Waltham, in the county of Middlesex and State erated upon, shall be uniform in speed. Es-

pecially is this true of the long ribbons or strips of steel, which on completion of the various and successive operations, isto be broken or cut into uniform lengths, suitable for individual main springs, in order that the entire length of along strip shall receive uniform treatment, either of grinding, polishing, tempering or coloring.

It is necessary that, in the treatment of articles of the form spoken of, the threads, strands, or ribbons should be wound upon some sort of spool, bobbin or reel, and, if the receiving reel or bobbin be revolved at a uniform rate of speed, each successive convolution or layer, being wound upon the preceding one, increases thecircumfereuce of the roll, so that the ribbons will be drawn on at a gradually increasing rate of speed, so that if the body of the bobbin were small, and the ribbon being wound upon it were of considerable length, the variation in the speed of the ribbon between the beginning and the end of the winding would be very considerable.

To secure a uniform speed in the movement of a ribbon of steel or other metal or material, is the object of my invention, which may be understood by the following description, together with the accompanying drawings, which form a part of this specification.

In all the views, like letters indicate the same parts. Y

Of the said drawings: Figure 1, is a perspective view of my improved apparatus, portions thereof being represented as broken away. Fig. 2 is a side view detail on an enlarged scale. Fig. 3, is a diagram representing a modified form of the invention. Fig. 4 is a perspective view of the friction cones, and illustrates the means forshifting the friction ring.

In the drawings: a designates a base or table, supporting the means for effecting the coloring of watch main springs. Of the' said means, I) designates a revoluble heater or stove. 'c is a burner connected with a gas pipe for heating the stove b. d designates the bobbin upon which the material to be colored or tempered is wound. e designates the winding-on bobbin which draws off the material from thebobbin of around the heater 1) and takes it up upon itself, all as will be more fully understood by reference to United States Letters Patent No. 459,914, granted to me, September 22, 1891.

f designates a shaft upon which is a gear g meshing With a gear it upon the shaft 2' of the I winding-on bobbin 6.

7 is a friction cone which is driven by a belt which passes about a pulley k on the shaft of the cone j.

Z is a driven cone which is operated by means of a friction ring or belt m which extends between the driving conej and driven cone Z, as is common in what is known as Evans friction cones.

n is a rod mounted in suitable bearings provided with a fork on the shaft which embraces the belt m, so as that the same may be shifted between the friction cones and vary the speed at which the conel may be driven, all as is well understood by mechanics generally acquainted with driving mechanism. v

o is a pulley secured to the shaft of driven cone Z, and p is a pulley secured to the shaft f, and belt q being passed about the said pul leys, whereby the shaft) is operated'from the shaft of the drivencone Z. 7

rdesignates a rod or shaft mounted in suitable bearings, so as to be longitudinally movable therein, and provided on its inner end with a roller or wheel 8 which rests and rolls upon the material wound upon the bobbin e. Connected with the outer end of the rod r is a rod or bar t which is attached at its upper end to ablock or box a adapted to be adj nsted in a bearing extending longitudinally of a bar '0 pivotally connected at its opposite end with a pulley 20, about which passes a band or belt 0:, the ends of which are so connected with the fork or other means whereby the band or belt m is shifted, that when the pulley w is rotated in one direction, the said band or belt m will be shifted toward the small end of the cone Z, and when the said pulley is movedin the opposite direction, the belt m will be moved toward the larger end of the said cone. The rodt is pivoted to a suitable support if and is pivotally connected at its upper and lower ends respectively with the bar 1; and the rod 0 lVith this construction and arrangement of parts, it will be seen that as the winding-011 bobbin fills, the rod 0* will be in the direction indicated by the ar row marked in proximity thereto in Fig. 1, moving-the bar 1; in the opposite direction, and gradually turning the pulley to, so as to move the band m toward the small end of the conej and operating the winding-on bobbin at a gradually reduced speed, correspondingto the diameter of the materialon the winding-on bobbin. A spring 3 connected at one end with the pulley w and at the other end with a stationary partof themachineor frame, tends to hold the roller or wheels against the woundon material. By making the connection of the bar t with the rod 7' adjustable, I am enabled to adjust the extent to which the belt or band an may be moved to suit circumstances. Any suitable means may be provided for this adjustment. As herein shown, the means consists of a screw .2 supported in suitable bearings, which screw is provided with a crank or handle for turning it, and is tapped through the block a.

I do not limit the scope of myinvention to the exact form of construction described and shown in the foregoing specification, nor do I restrict it to the use of coloring or tempering steel ribbons, as it is evident that it can be applied to other materials, and to a variety of operations.

If an electric motor should be employed for operating the winding-on bobbin, the outer end of the rod 0" might be provided with means communicating with a commutator a, as shown in Fig. 3, so as to reduce the strength of the electric current, in a well known way, as the winding-on bobbin becomes filled.

Having thus described the nature of my invention and explained a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its employment, I declare that what I claim is- 1. In an apparatus for giving a uniform rate of speed to a movable ribbon oristrand, the combination of the winding-on bobbin on which each successive convolution of ribbon is superposed or wound, a driving wheel connected with said winding-on bobbin, a sliding arm or rod having a roller at one end to bear against the outer layer or coil, a pulley and connections from said sliding arm to said pulley whereby longitudinal movement of the rod imparts a rotary movement to the pulley, speed changing mechanism and flexible connections from the periphery of said pulley to said speed changing mechanism, substantially as and for the purpose described.

2. In an apparatus for giving a uniform rate of speed to a movable ribbon or strand, the combination of the winding-on bobbin on which each successive convolution of ribbon is superposed or wound, a driving wheel connected with said winding'on bobbin, a sliding arm or rod having a roller at one end to bear against the outer layer or coil, a pulley and connections from said sliding arm to said pulley whereby longitudinal movement of the rod imparts a rotary movement to the pulley, a spring for moving said pulley in one direction, two friction cones, one of which receives power and the other of which is connected with the driving pulley of the winding-on bobbin, a friction ring interposed between the said cones, a sliding rod for shifting said ring and flexible connections from said ring shifting rod with the periphery of the said pulley, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 22d day of March, A. D. 1892.
